The dual tuners require analog cable. It is rather complex and costly to recreate analog cable the analog tuners can tune. It would be easier and cheaper to upgrade to a Premiere.
The Series 2 DT can only be set up for one box, period. Single tuner TiVos can be set for two boxes, but one box has to be satellite, the other cable, OTA, or IPTV (cable to TiVo setup), and only one at a time can be used.
Series 2 234 Hr Lifetime.
